I have designed surge protector with LTC4366.
I attached the schematic.
My problem is, when load current is 10A there is no problem. But i increased the load current to 15A LTC4366 stopped working and voltage across mosfets became near 2.5V.
Voltage between…
Hi Michael,
1. The 1.6uA is internal weak pull up source to keep the pin in a known state. you can pull down the shutdown pin externally that will overcome this 1.6 uA causing it to shutdown. If you don't want to use the shutdown functionality , you can…
Hello everyone. i have a supresor circuit with LTC4366CDDB-2#PBF, it work fine when the overvoltage is about 2 seconds, but when overvoltage pass more that 2 seconds the Ltc4366-2 never restart from cool-down period.
I have to turn off the source and…
Hello. I need help with LTC4366 circuit. I need to develop a supply that is protected from voltages upper then 30 V DC (up to 400 V AC) and that must work from 10 V DC, so I've chosen LTC4366 for this application. Now I'm trying to make it work, but than…
Hi,I think LTC4366 would do the job. I moved your query to Power By Linear for better support on your question.Best Regards,Goz
Hi John,
In the first case with 3.3nF gate cap, the inrush current is very small and it takes roughly 62 msec to charge the output cap . The timer timesout much before this and shuts the gate off. the part will still retry after 9 sec but fail to start as…
Hi
How does the example circuit of the LTC4366 handle ESD protection ?
Does the M2 Mosfet clamp the ESD pulse and survive ?
I would like to use the above design recommended in the LTC4366-2 Datasheet.The is a problem on cold crank 12V systems, that can drop to 4-6V during staring of the engine. Can I use a capacitor like 4u7 capacitor (100V ) to store more than 9V during…
Hi,we use the LTC4366-2 to protect an internal logic supply (low current required only) during MIL-STD1275 voltage surge (100V pulse with short rise time, 50ms Plateau and 450ms fall time). This works fine as expected, as the Duration of the pulse does…
Hello,
I wanted to us LTC4366-2 in my design. In the datasheet, there is an example circuit which can carry 1.5A current. In my application, I need to draw in between 20A to 60A current. By just changing the M1 (Mosfet), can I adopt the circuit to…
